Abstract

Seven Salmonella lytic phages found in water sample of river near UBB campus building. Phages were characterized by plaque morphology (plaque diameter size and shape) and phage host range. Phages formed plaques with diameter size ranges from 1.06 mm to 4.90 mm, and form shape such as small dot, circle, elongated, or irregular. Factors effect plaque forming by phages are phage titer number and incubation time. All phage isolates have broad host range include Gram negative and positive. Six phage isolates are able to lyse Salmonella, Staphylococcus aureus, and Escherichia coli, meanwhile one phage isolate is able to lyse Salmonella and Staphylococcus aureus.

Abstract

Kayu lubang are plants which one traditionally used to acne treatment. Scientifically acne is caused bacteria’s such as Propionibacterium acnes dan Staphylococcus aureus infection. The growth of Propionibacterium acnes and Staphylococcus aureus be inhibition with phytochemical compounds contained leaves of kayu lubang. The purpose of this research was to identification phytochemical compunds from rude extract ethanol leaves of kayu lubang and which consentration extract that shows the optimum to inhibition growth of Propionibacterium acnes dan Staphylococcus aureus in antibacterial activity test. Phytochemical test conducted qualitative and antibacterial activity test using disc diffusion with concentration 15%, 20%, 25%, 30%, 35% dan 40% in 3 replication. Based on the results showed that in general those leaves contain alcaloid, phenol, tannin and steroid. The optimum inhibition zone results of extract inhibition bacterial growth at concentration of 40%, inhibition zone Propionibacterium acnes inhibition zone of 6,83 mm while Staphylococcus aureus bacteria was 5,53 mm. Based on the results of statistical tests DMRT effects of extracts leaves of kayu lubang against the bacteria Propionibacterium acnes and Staphylococcus aureus showed significant differences among for 95% confidence.

Abstract

N availability in Indonesia is still relatively low. Various types of fertilization techniques are developed in order to reduce N losses, but the efficiency of N fertilizer use is not optimal. Therefore, biological N-belay technology is needed through Rhizobium inoculation to improve N fertilization in legume plants. This study aims to isolate and characterize Rhizobium bacteria from nodules formed in the roots of legume plants. The collection of Glycine max L. and Mimosa pudica Linn. root nodules is ashamed to be chosen from the pink root nodules. Rhizobium isolation using selective media of Yeast Extract Manitol Agar + congo red using the spread plate method. Characterization carried out, in the form of macroscopic observations, Gram staining, biochemical physiological tests, manufacturing growth curves and pathogenicity tests. The results of isolation from both plants obtained five types of Rhizobium isolates. The results of the characterization of isolates in both plants also showed the same thing, namely: bacteria have Echinulate shape when grown on sloping media, and when grown in cup media (large size, milky white, opaque (not penetrated by light, circular shape, convex elevation (convex), the surface is smooth shiny, the entire margin), including Gram negative bacteria, rod shaped, facultative anaerobic, motile, can degrade hydrogen peroxide, show positive oxidase, can ferment glucose and sucrose, grow well at pH 5 - pH 7, and not pathogenic to plants.

Abstract

Indonesia has been know as own high diversity of flora and fauna. In addition, Indonesia has been know high diversity of ethnics which has various distinctive traditions, including local knowledge. One of the local knowledge on using of traditional medicinal plants. The utilization of plants as medicinal plants has never been reported yet because of the changes of era, the local wisdom knowledge especially for medicinal plants has faded away. The purpose of this research is to determine the local knowledge of Jerieng ethnic in utilizing the plant include the parts of the plant, the processing, and the benefit as medicinal plants), collecting data of the medicinal plants diversity (species numbers, scientific name, local name, familes, habitat and habitus). The method of this research was used the qualitative and descriptive analysis. Data was collected from survey and interview in the Jerieng ethnic using snowball sampling. The result of research show there are 82 plants species 52 families, 16 informans, and 45 species disease. The most dominant families of medicinal plants is Zingiberaceae with 7 kinds and graminae//poaceae with 6 kinds. The most frequent used part of the plants by Jerieng ethnic are the leaf 46%, trunk habitus species 35% and the higher habitat is at plants garden house 52%. Meanwhile for the most used processing is by boiling the medicinal plants.

Abstract

Agroecosystem is form of ecosystem that is man-made.It is a part of ethnoecology as a way for traditional society to cultivate their land for agricultural purposes. The people of Namang Subdistrict has long applied their ancestors tradisional ecology knowledge in culvating their rice fields and gardens. Exploring this knowledge and surpassing it would be beneficial to humankind. To collect the data, the present writer conducted field observation and interview by using snowball sampling method and scientific study. Namang society cultivates rice fields and gardens based on traditional knowladge. Farmer’s rice agroecocystems believe in the moon and the to plant rice is very influential on natural conditions, because nature for them greatly influences the success of rice fields. The murok jerameh tradition is a thanksgiving for the abundant rice yields and begs god that the following year’s harvest is also abundant. Farmers agroecosystems believe that the existence of kiara (Ficus benjamina L) trees indicates that the land is fertile.
